Ten years performance guaranteed warranty

Periodically clean the threads and o-rings with a lint free cloth and apply a thin coating of EagleTac synthetic grease to the o-rings and threads. After prolonged exposure to moisture, the head and batteries should be removed, inspected, and dried. Do not touch or attempt to clean the reflector, as it will scratch the reflective coating permanently.
